The 34-year-old beauty has confirmed that she is engaged to her boyfriend of three months David via Instagram.

Kelly shared a snap of herself cuddled with her muscle-bound man while holding a balloon reading "Engaged!"

The model wrote: "Lovely Weekend in Wigan meeting my New extended Family…Such happy times and excited to share my life with the most wonderful man I've ever met."

The curvaceuous star hinted at a big event last week after she tweeted: "International Day of Happiness, it certainly is."

This bombshell comes just weeks after the pair SPLIT while enjoying a PDA-packed holiday in the States.

Kel was allegedly scared that her Gladiator beau was using her for a profile boost, with a source at the time claiming: "She felt hurt and humiliated when she realised he was more interested in fame than he was in her."

The Celebrity Juice regular deleted every pic of the couple on Instagram after they parted ways.

However, David, aka Tornado, denied these allegations, saying: "Media attention isn't a new thing. I’ve been doing a lot of modelling work in America myself, people know me out there."

This claim seemed to placate Kelly, who immediately reunited with her fella – and reportedly agreed to marry him in a few seconds, despite being left dumbstruck by his proposal.

A source told The Sun: "It’s still a closely guarded secret and came to Kelly as a massive shock. But she is at that time in her life now where she wants to make a commitment and she has fallen head over heels for David."

David, who at 27 is seven years younger than his missus, started dating the brunette bombshell after meeting her on New Year's Eve at her London club Steam and Rye.

After becoming her personal trainer, the beefcake reportedly moved into Miss Brook's lavish city townhouse after just a few weeks.

However, while Kelly certainly seems smitten, there's been a few celebs pointing out that Mr McIntosh is no stranger to hooking up with stars.

Bodybuilding minx Jodie Marsh publicly flirted with the Gladiator star last year, with David even asking the model on a date; while Chantelle Houghton claims the hunk also came onto her.

Kelly hasn't had the best of luck with starry relationships either – she was previously engaged to Titanic actor Billy Zane, but split after four years of dating.

The buxom beauty dated rugby player Thom Evans from 2010 until 2013, as well as going out with Jason Statham for seven years.

And famously, Kelly was cheated on by love rat Danny Cipriani, despite taking care of him after he was involved in a car accident.

Let's hope this tumultuous relationship works out a bit better.
